RUFFLING ATTACHMENT FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 689,997, dated December 31, 1901.

Application filed January 6, 1896. Serial No. 574,428. (No model.)

To all who/it it may concern.-

Be it known that LEDWIN J. TOOF,a citizen of the United States, and a resident of the city and county of New Haven, State of Connecticut, have invented new and useful Improvements in Rnffling Attachments for Sewing- Machines, of which the following description, taken in connection with the drawings herewith accompanying, is a specification.

My invention has for its object to provide a cheap, simple, and effective device for the purpose intended; and it consists in certain novel constructions and arrangements of the parts forming the device, as hereinafter set forth in detail, and pointed out in the claims.

Referring to the drawings, Figure 1 represents a side elevation of a ruffler constructed according to my invention. Fig. 2 represents an elevation of the side opposite that shown in Fig. 1. Fig. 3 represents an end view of the same looking from the right of the device as shown in Fig. 1, and Fig. 4 a perspective view of the ruffler-blade and its connected lever detached from the ruffler.

To explain in detail, a represents the supporting plate or frame, upon which the several parts forming the attachment are supported. This frame a in the present instance illustrated consists of a base-plate a, which is adapted to be detachably secured in a rigid position upon the cloth-plate of the machine, the means for securing such connection consisting, as herein shown, of a lip a and a threaded pin 0 both located on the under side of said base-plate and adapted to be inserted through openings located in the clothplate of the machine and be held in such position by a nut engaging with said threaded pin on the under side of the base-plate in a manner as will be readily understood. Any suitable means for securing such connection may, however, be employed. The said baseplate a is provided with an integral part or extension at one side thereof, which extends upward and over the base-plate, as at or, which overhanging portion is substantially parallel with the base-plate and provided with a vertically-arranged arm a, to which latter at the upper end thereof is pivotally secured a vertically-arranged lever 12. This lever 17, which is vibrated in a manner as will hereinafter be described, is provided with alateral extension 12' at its lower end, having a plate I) pivotally connected therewith, to which plate is rigidly secured the ruffling-blade 19 The forward or working end of the latter is held in operative position to bear upon the separator-plate 0, located immediately beneath the same, by means of an arm or part b of said plate extending laterally therefrom and beneath the upper or overhanging portion a of the supporting-plate a, as clearly shown in Figs. 1 and 2, in which position it moves and holds the working end of the rufliing-blade in its said operative position, as described.

The vertical lever 12 is operated to reciprocate the ruffiing-blade b by means of a horizontally-arranged lever d, which is also pivotally secured upon the vertical arm a of the supporting-frame. This lever 01 is provided at one end thereof with a catch device 6 for detachable connection with the needlebar from which the lever is operated, and at its opposite end said lever is formed with a part thereof, as at d, extending between two contact or bearing surfaces d and (1 with which the lever b is provided for engaging with the same to give a vibratory movement to the said lever 11. One of the said contactsurfaces is formed by an adjusting-screw f as a means whereby the distance between the same may be varied and the throw of the le-' ver adjusted accordingly.

h represents the usual supplemental spring presser, which is adapted to extend beneath the presser-foot of the sewing-machine and is attached at one end upon the supporting-plate at t i represents a laterally adjustable edgeguide,which is pivotally secured at one end upon the supporting-plate and in the space between the upper and lower parts of the same, as shown.

Having thus set forth my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a ruffling attachment for sewing-ma chines, a frame formed of one integral piece bent upon itself to form a lower base-plate and an upper overhanging portion the end of which is bent upward to form a vertical arm, a lever pivotally supported upon said arm, a plate pivotally connected with said lever,hav

ICO

ing a rufller-blade and a laterally-projecting arm extending into a position beneath the said overhanging portion of the supportingframe to hold the free end of the ruffler-blade in operative position, and means for operating said lever.

2. In a ruffling attachment for sewing-machines, a frame formed of one integral piece bent upon itself to form a lower base-plate for connection with a machine,and an upper overhanging parallel portion the end of which is bent upward to form a vertical arm, a vertically-arranged lever pivotally supported upon said arm, a plate pivotally connected with said lever at one side thereof having a rigidlyattached ruffler-blade and provided with a laterally-projecting arm extending beyond the opposite side of said lever to a position beneath the stationary overhanging extension of the supporting frame against which it slides to hold the ruffler-blade in operative position, and means for operating said lever, substantially as described and for the purpose set forth.

3. In a rufliing attachment for sewing-machines, a frame formed of one integral piece bent upon itself to form a lower base-platefor connection with a machine,and an upper overhanging parallel portion the end of which is bent upward to form a vertical arm a vertically-arranged lever pivotallysupp'orted upo u said frame having its lower end extended laterally at rightangles thereto,the plate b ,having an attached ruffier-blade, pivot-ally connected with said lever extension at one side of the lever and provided with the arm 17 extending beyond the opposite side of the lever to a position beneath the said overhanging portion of the supporting-frame, the engaging end of said arm b being arranged in a horizontal plane and at an angle to the plate b substantially as described and for the purpose set forth.
